Boat slip during bunker replacement

[dwayneb]

Anyone know or have the best method of replacing carpet on trailer bunks...do you try renting a slip? My lund is 21ft and around 3,000lbs. Trailer bunks are pretty long...I've heard of guys making a jig and jacking up the boat high enough to get the old bunks off but with an aluminum boat of this size im not so sure...

Thoughts please?
